Rubio sat outside Olivia Sievers hotel and waited for her patiently every time she visited.
Grab a tissue already, this story about soulmates - one human and one dog - will leave you all misty eyed for the best reason possible.
Olivia Sievers, a German flight attendant, regularly travelled to Argentina for work. Months ago, during one of her work trips to Buenos Aires, she met a stray dog who she bonded with and named Rubio. Now, she's adopted Rubio and taken him home.
According to the Facebook page Mascotas Puerto Madero Adopciones Responsables, Ms Sievers met Rubio by chance while walking around the city. She decided to feed him and played with him a while. For Rubio, it was probably love at first sight and he began following her around after their little encounter. He even sat outside her hotel, waiting patiently.
Ms Sievers left for work but days later, there he was outside her hotel again when she returned to Buenos Aires. The two had really bonded in that little time together.
Eventually, concerned for his well-being, Ms Sievers contacted the animal shelter who took Rubio in. That wasn't going to keep him from meeting his human - on her next trip to Buenos Aires, there Rubio was again waiting to greet her outside her hotel - he had apparently escaped the shelter to do so.
Eventually Rubio's unfaltering affection for Ms Sievers wore her down and she decided to adopt him and take him back with her to Germany.
Now, Rubio is enjoying his new home and family in Germany.
